Strand/Pedestal Mounting With Extension Mounting Brackets (EMBs)
Use EMBs to mount a Flex Max901e if additional space is required between the unit and the strand.
The following kits are available:
■
3.2-inch (8 cm) EMB (P/N 172187-01)
■
6-inch (15 cm) EMB (P/N 172187-03)
Strand diameter determines the orientation of the strand clamp. Refer to Figure 4.5.

To strand/pedestal mount with EMBs
1. Attach the EMBs to the top strand clamp bosses (mounting surfaces) with the 1/2-inch
(1.27 cm) long EMB bolts and lock washers (see Figure 4.5). The flat face of the EMB mates
with the top strand clamp boss. Tighten the bolts until the EMBs are snug but can still be
adjusted.
2. Attach the strand clamp assemblies to the EMBs with the 1-inch (2.54 cm) long clamp bolts,
o-rings, lock washers, and nuts. See Figure 4.5.
3. Hoist the housing to the strand and hang it in position.
4. Tighten the clamp bolts so that the housing cannot come off of the strand, but is still free
to be adjusted.
5. Position the housing at a location on the strand that is accessible for attaching cables and
performing maintenance and balancing, and that complies with the requirements of the
system.
6. Torque both the clamp and EMB bolts to between 40 and 66 in-lbs (4.5 and 7.5 N·m).
Note EMBs are not included with the unit but may be purchased separately. Contact

mounting hardware:
■
1/4-20 UNC x 1/2-inch bolt
